This invention relates to new and useful improvements in valves and'theprimary-obict or the present invention is tofprovide al novelaand 3 without restricting the flow of fluid through the passage.

A further object of the present invention is to provide a manually operated and regulated valve including a valve chamber having a removable closure thus permitting a scraper or cleaner to be extended through the chamber and into a pipe line to clean or scrape the latter.

i A still further aim of the present invention is to provide a valve of the aforementioned character that is simple and practical in construction, strong and reliable in use, small and compact in structure, relatively inexpensive to manufacture,

and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a longitudinal vertical sectional view taken substantially on the plane of section line 1-! of Figure 2;

Figure 2 is a longitudinal vertical sectional view taken substantially on the plane of section line 2-2of Figure 1;

Figure 3 is a transverse horizontal sectional view taken substantially on the plane of section line 3--3 of Figure 1; and,

Figure iris a diagrammatic view showing the manner in which a scraper is applied through the chamber portion of the present invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I0 represents a body having from the body 10 intermediate the ends thereof,

chamber.

A gasket 44 carwrench 48 for rotating the rod 33 to actuate the valve 20.

The inner wall of the body 10 is provided with arcuate semi-circular rounded edges 50 and 52 the lower semi-circular portions 54 and 56 of whichare straight to seal the lower end of the valve 20 when the same is disposed in a closed position.

In practicaluse of the present invention, the annular beveled edge 22 of the valve 20, when raised partially or completely, will tend to cut and prevent any material from clogging in the body l0 and the straight edge 54 and 56 of the body [0 will also prevent material from clogging in the body 10.

When it is necessary to clean or scrape the inner walls of pipes 58 that extend from the body In, the closure I6 is removed from the chamber M, the valve 20 and rod 30 are removed from the chamber 14, and a scraper 60 and a flexible line 62 are quickly and readily extended through the chamber [4 and body In into the pipej58.

preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is: r

A manually operated back sewer valve comprising an elongated body having a longitudinal passage extending therethrough, a chamber fixed to and projecting outwardly from thebody intermediate the ends of the body and intersecting the passage, said chamber having a removable closure at its end remote from the passage, a valve seat located with the wall of the passage spaced from and in registry with the other end of said chamber, a soft metallic lining in said seat and having a beveled peripheral edge, a hollow cylindrical valve vslidably received in said chamber and having a beveled peripheral edge'facing said lining and 'complemental to the bevelededge of said lining for engaging said bevelededge of said lining as the valve is moved to its closed position in the passage, an operating rod extending axially end of said valve remote from the beveled edge of said valve and having a channeled groove receiving said spherical element, a gasket fixed to said lug and overlying said groove, said gasket havingan aperture receiving the reduced end of said rod and retaining the spherical element in said groove, said lug having a pair of spaced parallel horizontal bores intersecting said groove at right angles, and pins fitted in said bores and confining the'spherical element therebetween.
